[0001] The present application claims priority to Chinese Patent Application No. 201910785612.9, entitled "INFORMATION COMMUNICATION METHOD AND APPARATUS", and filed to the China Patent Office on August 23, 2019, the entire contents of which are incorporated herein by reference.
Field
[0002] The present application relates to the technical field of communication, in particular to an information communication method and apparatus.
Background
[0003] In order to improve the coverage at the edge of a cell and provide a more balanced quality of service in a service area, multi-point coordination is still an important technical means in a new radio (NR) system. From the perspective of network morphology, network deployment with a large quantity of distributed access points and base band centralized processing will be more conductive to providing a balanced user experience rate, and significantly reduce the delay and signaling overhead caused by hand-off. With the increase of frequency bands, relatively dense deployment of access points is also required from the perspective of ensuring network coverage. In a high frequency band, with the improvement of the integration of an active antenna device, a modular active antenna array will be more preferred. The antenna array of each transmission reception point (TRP) can be divided into several relatively independent antenna panels, so the shape and port quantity of the whole array can be flexibly adjusted according to the deployment scenario and service requirements. The antenna panels or TRPs can also be connected by optical fibers for more flexible distributed deployment. In a millimeter wave band, with the decrease of wavelength, the blocking effect caused by obstacles such as human bodies or vehicles will be more significant. In this case, from the perspective of ensuring the robustness of link connection, the cooperation between multiple TRPs or panels can also be used to transmit/receive multiple beams from multiple angles, so as to reduce the adverse impact caused by the blocking effect.
[0004] In the multi-point cooperative transmission of multiple downlink control information (DCI) scheduling multiple physical downlink shared channels (PDSCHs), there is no clear solution to the specific reporting mode of physical uplink control channel (PUCCH) reporting.

Detailed Description of the Embodiments
[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, obviously, the described embodiments are only a part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present application.
[0024] At present, multi-TRP /panels support two transmission types, namely single DCI scheduling and multiple DCI scheduling.
[0025] The single DCI scheduling: scheduling a PDSCH through a physical downlink control channel (PDCCH).
[0027] When multiple pieces of the DCI are used for scheduling, multiple PUCCHs may be used to report respectively, or one PUCCH may be used for joint reporting. When independent reporting is performed through the multiple PUCCHs, codebooks for reporting need to be generated respectively; and when joint reporting is performed through one PUCCH, it is necessary to determine how to generate a joint codebook. At present, a higher layer may configure corresponding ID (H-ID for short) for a control resource set (CORESET) that schedules the PDSCH. It should be noted that the ID is different from the CORESET ID (C-ID for short). When independent codebooks are generated, values of the two C-IDs are different, and the scheduled PDSCHs respectively correspond to an independent codebook.
[0028] The codebook here refers to the arrangement of bits of HARQ feedback information (the feedback information includes: ACKnowledge (ACK)/negative ACKnowledge (NACK), and ACK/NACK is referred to as AN) when reporting through the PUCCH. That is, according to the structure of the codebook, a terminal needs to sort and report the AN bit corresponding to data at each PDSCH transmission moment on each component carrier (CC) that needs to be reported on the same slot.
| Slot 1 | Slot 2 | |
| CC1 | AN of PDSCH 1(1,2) | AN of PDSCH 3(3,5) |
| CC2 | AN of PDSCH 2(2,2) | AN of PDSCH 4(4,5) |
| CC3 | AN of PDSCH 5(5,5) | |
| DAI (cDAI, tDAI) | ||
[0029] A downlink assignment index (DAI) in Table 1 is indicated by the DCI, where cDAI represents the serial number of data sent on the slot. For example, there are scheduled data on CC1 and CC2 on slot 1 in Table 1, and their cDAIs are 1 and 2 respectively. tDAI indicates the total quantity of scheduled data up to the slot. For example, the total quantity of data scheduled by all CCs on the slot 1 in Table 1 is 2, so tDAI=2. The terminal acquires the above codebook through the DCI, and for the corresponding PDSCH in the codebook, AN information on the same slot needs to be reported. Therefore, the terminal can arrange the corresponding AN bits of each PDSCH together according to the order of the AN bits determined in the codebook and report through the PUCCH.
[0030] If the joint reporting mode is adopted, the two codebooks may be cascaded, or a joint codebook may be synthesized in an interleaving mode. The so-called cascade mode means that the order of the AN bit is determined according to the respective codebook, then the order of the AN bit for a certain TRP is arranged first, and the order of the AN bit for another TRP is arranged behind. The interleaving mode means that the PDSCHs with the same CC and the same transmission slot are arranged in a preset order. For example, Table 2 shows an example of the joint codebook generated by the interleaving mode.
| Slot 1 | Slot 2 | |
| CC1 | AN of PDSCH 1 from TRP0(1,2) | AN of PDSCH 3 from TRPO (3,5) |
| AN of PDSCH 1 fromTRP1(1,1) | AN of PDSCH 2 from TRP1 (1,3) | |
| CC2 | AN of PDSCH 2 from TRP0 (2,2) | AN of PDSCH 4 from TRP0 (4,5) |
| AN of PDSCH 3 from TRP1 (2,3) | ||
| CC3 | AN of PDSCH 5 from TRP0 (5,5) | |
| DAI (cDAI, tDAI) | ||
[0031] When a resource used for PUCCH transmission is determined, the last piece of DCI received by the terminal shall prevail. That is to say, if the terminal receives scheduling information of the multiple PDSCHs, the HARQ feedback for these PDSCHs is performed on the same time domain resource, then the resource used for HARQ feedback on the above time domain resource is indicated by the last piece of DCI received by UE among DCI that schedules these PDSCHs.
[0032] However, in the existing multi-point cooperative transmission of multiple DCI scheduling multiple PDSCHs, the PUCCH reporting has the following problems without clear solutions:
how to switch between the joint reporting and the independent reporting: that is, under what circumstances, what mechanism is used to switch; and
during joint reporting, how to determine the order of the AN information reported by each TRP.
[0033] During joint reporting, if the terminal receives scheduling information of multiple PDSCHs (corresponding to different pieces of DCI), the HARQ feedback for these PDSCHs is performed on the same time domain resource, and the sending times of the last few pieces of DCI are the same, then the terminal cannot distinguish which DCI is the last piece of DCI, and consequently, the resource used by the PUCCH cannot be determined.
[0034] Therefore, the embodiments of the present application provide a method and apparatus for reporting by using the PUCCH when multi-TRP/panels are used for cooperative transmission.
[0035] The method and the apparatus are based on the same application concept. Since the method and the apparatus have similar principles for solving the problems, the implementation of the apparatus and the method can be referred to each other, and the repetition will not be repeated.

Based on different specific application scenarios, the base station may also be referred to as an access point, or may refer to a device that communicates with wireless terminal device through one or more sectors on an air interface in an access network, or other names. The network device may be used to convert the received air frame and Internet protocol (IP) packet to each other, as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an IP communication network.

[0039] Hereinafter, each embodiment of the present application will be described in detail with reference to the accompanying drawings of the specification. It should be noted that the display order of the embodiments of the present application only represents the sequential order of the embodiments, and does not represent the pros and cons of the technical solutions provided by the embodiments.
[0040] In the embodiments of the present application, a terminal may jointly determine whether to use a joint reporting mode or an independent reporting mode to report HARQ feedback information according to higher-layer configuration and time domain resources. The terminal determines the reporting mode according to the higher-layer configuration at the network side and the time domain resources, and reports the HARQ feedback information by using the determined reporting mode.
[0041] For example, if the network side indicates multiple PDSCHs to report the HARQ feedback information through the PUCCH on the same time domain resource (which may be slots or sub-slots), the AN is reported through the PUCCH by using the joint reporting mode on the above time domain resource; and
if the network side indicates each PDSCH to report the AN through the PUCCH on different time domain resources, codebooks are independently generated and reported for each PDSCH according to the AN codebook generation mode of existing version Rel-15, that is, the HARQ feedback information AN is transmitted by using the independent reporting mode.
[0042] The specific transmission process of the HARQ feedback information includes, for example: the network side configures the reporting mode of the terminal as joint reporting or independent reporting through control signaling.
[0043] 1. If the reporting mode configured at the network side is joint reporting, then: if the network side indicates multiple PDSCHs to report the HARQ feedback information through the PUCCH on the same time domain resource (which may be slots or sub-slots), the AN is reported through the PUCCH by using the joint reporting mode on the above time domain resource.
[0044] Two codebooks may be cascaded or combined in an interleaving mode when a joint codebook is determined (see the background for details). In this process, an order needs to be determined. For example, for the cascade mode, the order determines the AN sequence of the PDSCH scheduled by which CORESET is the first, and the AN sequence of the PDSCH scheduled by which COREST is the second; and for the interleaving mode, the order determines the AN bits corresponding to each PDSCH transmitted on the same CC and time domain resource, the AN sequence of the PDSCH scheduled by which CORESET is the first, and the AN sequence of the PDSCH scheduled by which COREST is the second.
[0045] If a higher layer configures two H-IDs with different values (the ID configured by the higher layer for CORESET scheduling the PDSCH), in the process of determining the above order, the above H-IDs may be used to distinguish the order. For example, the AN sequence or AN bit corresponding to the CORESET for which the value of the H-ID is small is ahead.
[0046] If the higher layer configures two H-IDs with the same value, or does not configure the H-ID, the TRP order may be determined by using one of the following modes.
[0047] Mode 1: the TRP order is determined according to a size of a CORESET identifier (C-ID for short) corresponding to the DCI.
[0048] For example, the AN sequence or AN bit corresponding to the CORESET for which the value of the C-ID is small is ahead.
[0050] For example, for the cascade mode, in any information field of the DCI, the CORESETs from different TRPs have different values, and the CORESETs from the same TRP have the same value. The AN sequence corresponding to the CORESET with a small indicated value is ahead; for the interleaving mode, in any information field of the DCI, the AN sequence corresponding to the DCI with a small indicated value is ahead.
[0051] Mode 3: for the interleaving mode, the order of the AN bit may be determined according to the time when the DCI is detected.
[0053] If the higher layer configures two H-IDs with the same value, or does not configure the H-IDs, a PUCCH resource indicated in one piece of DCI may be determined according to one of the following methods.
[0054] Method 1, the HARQ feedback information is reported according to a PUCCH resource indicated by the DCI sent in the last if the sending times of the respective DCI are different.
[0055] Method 2, a PUCCH resource indicated in one piece of DCI is determined according to the size of the C-ID to report the HARQ feedback information if the sending times of the respective DCI are the same. For example, a PUCCH resource indicated by the DCI in the CORESET with the largest C-ID is selected to report the HARQ feedback information.
[0056] If the network side indicates each PDSCH to report the AN through the PUCCH on different time domain resources, codebooks are independently generated and reported for each PDSCH according to the AN codebook generation mode of existing version Rel-15 (even if it is configured as joint reporting, the AN reporting of each PDSCH does not have to be gathered together, so there is little change to the existing specification).
[0057] 2. If the network side configures the reporting mode as independent reporting, the terminal generates the respective codebooks of each ID according to the two different IDs configured by the higher layer, and reports through the respective PUCCHs of each ID.
